ahead here on cnn. there are new developments also in libya tonight. two extremist militia groups are disbanding and shutting down bases in eastern libya in response to counter protesters' demands. those counter-protesters rallied last night in benghazi against groups they say are responsible on the attack against the u.s. consulate that killed four americans. >> pro-democracy demonstrators began taking the situation into their own hands and storming various headquarters of known extremist militias in the city of benghazi. >> counter-protesters were met by some resistance. four people were killed and dozens injured last night in benghazi. more in libya in about three minutes here on cnn. at least 220 people were killed today in syria with government forces shelling aleppo and the damascus suburb. this comes as leaders of the rebel free syrian army are moving from turkey into syrian

territories. it's a milestone for the group who has many ex-soldiers who defected from president bashar al assad's army to fight the regime. the leader says the next step is to start liberating damascus. the wife of a missing retired fbi agent hopes to meet with the president of iran to plead for her husband's safe return. robert levenson disappeared on kish island in 2007 while investigating cigarette smuggling for a private company. now billboards with levenson's pictures are up in new york's time's square in hopes ma ahmadinejad will see them. >> 33 years of service to the united states deserves something. >> iran's president has repeatedly turned down meeting

an end to these extremist militias whom people and the government here say were in fact behind that attack that took ambassador stevens' life and the life of three other americans. what happened is that at night on friday hundreds of these pro-democracy demonstrators began taking the situation into their own hands and storming various headquarters of known extremists militias in the city of benghazi, including the headquarters of the militia. and the libyan government says it has detained individuals who are part of the association on the u.s. consulate, although they say the group as a whole was not behind that assault. >> cnn's arwa damon reporting there. it's getting close. just 45 days until election day, president obama back on the campaign trail in wisconsin. >> barack obama!

>> he held a rally this just the last hour in milwaukee. and earlier today he held a couple of fundraisers with home run king hank aaron. he hit a familiar theme with the crowd in milwaukee, hammering mitt romney over his plan for tax cuts. >> he thinks that if we just spend another $5 trillion on tax cuts for the wealthiest americans, all our problems are going to go away. jobs and prosperity will rain down on everybody, deficits will magically disappear. it will all end happily ever after. but there is a problem with that. we tried what they're selling. we tried it for a decade. it didn't work then and it won't work now. >> mitt romney also on the road, but he is working out of sight. he is holding fundraisers in california, raising some campaign cash. here is romney's number two, paul ryan spending the day in florida. several hours ago he held a town hall in orlando, and this

[ female announcer ] with cisco at the center... working together has never worked so well. so i brought it to mike at meineke. we gave her car a free road handling check. i like free. free is good. my money. my choice. my meineke. breakthrough medical news to tell you about that could mean the difference for life and death for thousands of cancer patients. the world's largest cancer center announced it's just years away from radically reducing the death rates from some of the most common types of cancer. cnn's chief medical correspondent dr. sanjay gupta got exclusive access inside the lab of the m.d. anderson center. >> can you translate? >> reporter: rosalyn austin is 23 years old.

she was halfway through her last year of college last december when she noticed something strange in her left breast. >> something was not right, and i knew it wasn't. it just -- i just felt like it was something not good. >> reporter: two doctors told her not to worry, but a biopsy revealed the truth. it was cancer. rozlyn lives outside dallas, but her father, an x-ray technician insist they'd drive six hours to houston and m.d. anderson. the first thing you notice when you get here, this place is big. in fact, a whole city devoted to fighting cancer. hallways, like highways here. and if you're walking, stick to the side. that's the part with the blue stripes. more than 100,000 patients every year. nearly 20,000 employees, more than a thousand clinical trials, all of it going on at once. and now dr. ronald depino, m.d. anderson's president says we are at a turning point. >> we're in a position to make

dramatic impact on cancer mortality in this decade. >> you're saying if we do everything right, in five years from now, there will be far fewer people dying from cancer? right? >> correct. i think with the existing knowledge and the application of what we now know, we could begin to see dramatic declines in mortality that would accelerate in years five through ten. and beyond set the stage for ultimate control of the disease. >> reporter: he calls it the moon shots program. they're pouring in $3 billion over ten years at a time when national funding for cancer research is flat. so how will it save lives? you might think it's all about wonder drugs. but what strikes me is that the biggest promises involve things that are much more basic. >> when people talk about curing cancer and wrestling this disease to its knees, they really think in terms of having that magical cocktail for a patient with advanced disease. it's much more than that. >> reporter: take lung cancer.

that's the biggest cancer killer of men and women. it's also the first cancer on the list. >> so if you catch stage 1 lung cancer, you're dealing with about a 20% mortality as opposed to advanced stage cancers where you're dealing with about 10% survival. so just by shifting the stage, you have an opportunity to impact on 170,000 deaths per year. >> reporter: he is talking about screening. but screening does have a downside. false positive test results leading to invasive procedures, even surgery for patients who turn out not to have cancer. recent studies show, though, if you focus on current or former heavy smokers, that downside is smaller. more of the suspicious findings really are cancer. >> figuring out who to screen, in this case heavy smokers can make a huge impact? >> a huge impact. >> reporter: or look at melanoma. >> when you sort of forecast now

a few years into the future, and this is a big moment as you're describing for m.d. anderson, is there a particular cancer where you think there is going to be the greatest impact? >> well, the one i'm most excited about is melanoma. >> reporter: i got an exclusive look at experimental therapies that in a handful of therapies are actually reversing a disease that even now is usually fatal once it spreads. it's vitally important science. but m.d. anderson says will save even more lives through systematic screening and basic prevention, like keeping kids out of the sun. >> we know from a pilot study in germany that a seven-year intensive screening for skin lesions led to a 50% mortality in melanoma. there is no drug that does that. >> also on the moon shot list are prostate cancer and two types of leukemia. there are new medicines and a growing understanding of the genes involved. also targeted triple negative ovarian cancer and triple

negative breast cancer, like rozlyn's. these cancers are aggressive, but depinho says our understanding of genetics are now at a point where doctors can make rapid progress developing and using the right treatments. >> i came back positive for braca 1. >> reporter: rozlyn is fortunate in that she caught her cancer early. and after surgery and chemotherapy, her doctors say the tumor is gone. her goal is to be a pediatrician. an for now she is devoting her time to helping other patients. >> i tell people i see a bright future ahead of me. so i'm going to get right back into school and act like this pretty much never even happened. >> reporter: dr. sanjay gupta, cnn, houston. >> and there are some promising news to tell you about one of america's favorite tv personalities. i'm happy to report that abc's robin roberts is feeling energized. the bone marrow transplant from her sister only took about five minutes on thursday. the next five to seven days will

be crucial ones, and she may be in the hospital for a month. they're watching closely to see if the transplant takes, and for possible infection. the "good morning america" host is battling a rare blood disorder she got because of earlier treatment for breast cancer. wishing you well, robin. in the nuclear standoff with iran, we keep hearing about this red line, essentially the no turning back point. ahead, how the two men running for president feel about the issue. they don't feel the same way. on every one of our cards there's a date.

a reminder... that before this date, we have to exceed expectations. we have to find new ways to help make life easier, more convenient and more rewarding. it's the reason why we don't have costumers. we have members. american express. welcome in.

there is no doubt about it. how the u.s. handles a country that crosses a red line has become part of the race for the white house. cnn guess in-depth on the issue of foreign policy to see where president obama and mitt romney differ over two looming issues internationally -- iran's nuclear program and the civil war in syria. the specifics from pentagon correspondent barbara starr now. >> reporter: president barack obama and governor mitt romney agree on two crucial national security issues. iran will not be allowed to go nuclear, and syria will not use its chemical weapons. but if it looks like either

might happen, they differ on what could trigger sending u.s. troops into action. on syria -- >> we have been very clear to the assad regime, but also to other players on the ground that a red line for us is we start seeing a whole bunch of chemical weapons moving around or being utilized. that would change my calculus. that would change my equation. >> reporter: the white house won't say what it will do if the red line is crossed. seizing dozens of chemical weapons sites would be tough, requiring tens of thousands of troops on the ground. romney has openly called for covert action. >> i would instead of watching what is happening in syria from a dispassionate distance, i would be leading in syria by encouraging our friends there like the turks and the saudis to provide insurgents to in syria.

>> reporter: but he too hadn't said how or when he would use u.s. troops. the bottom line on syria, president obama's red line moving or using chemical weapons. governor romney advocates greater u.s. involvement now. on iran, the candidates agree. iran cannot be allowed a nuclear weapon. >> we are determined to prevent iran from acquiring a nuclear weapon. >> romney has a different tape. >> clearly we all hope that dem diplomatic and economic pressures put on iran will persuade them from becoming a nuclear capability nation. >> reporter: the bottom line on iran, president obama says the regime would have to take direct steps to acquire a nuclear weapon. for governor romney, the red line merely having a nuclear capability without actually moving ahead to produce a weapon. but in the case of iran, many believe the red line already has slipped. >> we said that any enrichment was unacceptable in the case of

iran, and yet here they are with hundreds of kilograms, if not thousands of material. >> reporter: neither candidate is advocating war with syria or iran. both of them, in fact, have expressed hope that the sanctions will work. but if the red lines get crossed, both of those countries pose serious national security challenges to the united states. barbara starr, cnn, the pentagon. >> all right, barbara. and remember, for in-depth coverage of the election campaign, just go to cnn.com, cnn.com. you can get all the information there. a flight for the history books. the space shuttle "endeavour" made its mark this week, becoming the final shuttle to take to the skies this time on the back of a 747. aren't those pictures beautiful? can't look at them enough.

survival sex. trading sex for a warm meal or a place to stay. the term is disturbing enough. it's even more disturbing when it involves 13-year-olds trading sex just to stay alive. and this is not happening in faraway places. it's happening in cities and suburbs around america. teens being kidnapped and forced into prostitution. in minnesota, a state the fbi ranks as 13th in the nation for child sex trafficking. >> we're a few blocks away. >> reporter: police sergeant grant snyder has spent nearly two decades combatting sex trafficking in the midwest. >> white dodge caravan. >> reporter: in the van is a convicted pimp. he is about to violate

probation, meeting with a prostitute he picked up online. >> police, search warrant. >> reporter: the transaction is under way when sergeant snyder and his team enter, confiscating potential evidence. >> got a bag here. it appears to have condoms, a couple thousand dollars in cash. >> reporter: is that a normal amount of money? >> considering she has been here for a day, this is more than one client. minnesota is a place where a lot of women, a lot of girls are recruited into the sex trade. >> reporter: millions travel these highways known as spaghetti junction, arguably the crossroads for those in the midwestern sex trade, its hundreds of conventions and year-round sporting events. trafficking is online is so brazen, ads offer game-day specials. minneapolis/st. paul among the top 13 cities in the nation for child prostitution and adolescent sex trafficking. >> we had this misconception that the children that are being trafficked are not the children that live in our communities. and all the time what i see is that they come from our communities.

>> we hear sex trafficking, you think international victims. and when you say prostitution, you think of domestic, usually women that have choices. but the average age of entry is between 12 and 14. >> reporter: teens more emotionally vulnerable than adults get coerced and forced into the sex trade without realizing it at first. the majority of these children are runaways. when they disappear, few notice. survival sex is not uncommon. teens trading sex for a warm meal or place to stay. >> imagine being 13 years old, you're a runaway. you don't have money for food. you don't have a credit card you. don't want to go back home, because what is going on at home may be worse you feel than what is going on out here. >> not knowing where your daughter is or your child, absolutely terrifying. i had nightmares, you know. i would wake up and go to work in the morning, and she would be dead on my front stoop. >> reporter: she asked we not use her real name. so we'll call her violet.

her daughter ran away when she was 14. what do you understand of her live on the run? >> i just know that she was doing what she had to do in her mind to survive. >> reporter: vulnerable and alone, the teen was a perfect target, later telling her mom she was spotted by a man at a bus stop. >> and he saw her, and he approached her, wanted to know if she wanted to go hang out with him and his girlfriend. she got in the car with him, and that's where it all started. >> they don't say they're pimps. they say they're boyfriends. so it's very easy to lure somebody into believing that this person doesn't mean any harm for me. >> reporter: like many teens, by the time violet's daughter realized, it was too late. >> threats were made that if she told anything about what she was doing, or told on him that he would come back and kill her family. >> and she believed him? >> she believed him.

>> reporter: this is a story carter hears over and over. her group breaking free has helped hundreds of women and girls escape the sex trade. carter says teens are forced into prostitution by someone they initially trust. and like victims of international sex trafficking, american girls are kept isolated and moved from place to place. >> many young girls that get lured into prostitution end up in other cities, other states. and people don't realize that. it's very hard once they have been taken to find them. >> reporter: roughly 1.7 million children runaway every year. the figure was quoted by advocates, though difficult to confirm independently is within 48 hours of being a runaway, a teen will likely be approached by a pimp or someone in the sex trade. that's why officers at manhattan's port authority police department work tirelessly to find hundreds of teenaged runaways first before the pimps and traffickers. the missing around the country are too many to name. >> for people who are looking to

exploit kids, they'll throw a broad net out. it's not that they're just looking to get one or two kids at a time, while they are campaigning for one or two kids at a time, what they're doing is they might be speaking to as many as ten kids a day. >> you can't rely on people you don't know. >> reporter: this teenager from the midwest turns up with two friends and only $5 to meet a stranger. >> you know, i call the mother up. the mother is petrified. the mother wants her home. >> reporter: at 17, the girl is considered an adult in her state, and is therefore released. >> i said you don't know where you're going. you don't have no means of support. you don't know who this person is. he could be a serial killer. >> the worst part was the torture i had to hear about. >> reporter: was this torture by pimps? by men that she had to have sex with in order to survive? >> both. both. mainly the pimps. getting burned with cigarettes, cigars, getting hit in the head with snapple bottles, you know,

maybe she didn't bring enough money in or maybe she didn't do what she was told by him so she got beat up. >> reporter: the internet has changed the sex trade. girls no longer need to walk the streets. customers simply find them online. teens like violet's daughter are advertised through classified like this one, captioned "hot and sexy little pleaser." with more than $28 million in ad revenue in the last 12 months, backpage.com, the national advertising website, has been called a hub for prostitution. >> that was really where the pimp set out to the world that the services of this young woman were available. >> reporter: what your initial reaction when you clicked on escorts? >> i was actually disgusted. all i saw was naked behinds, naked breasts. >> reporter: minnesota prosecutor mike freeman says the girls advertised online are

forced to have sex with numerous men a night. the trafficker sets the price and gets the cash. how much money are these men making? >> too much. it's really hard to tell how much. but my guess is his lifestyle was pretty good. >> reporter: a couple thousand a week? >> oh, sure. >> reporter: how much did the girls get? >> usually not much, if they get anything. >> reporter: online classified like backpage.com also profit, charging a fee for every ad posted. but the website's attorney liz mcdougal says backpage isn't putting profits before safety, and in fact works with law enforcement to eliminate sex trafficking. >> we're not in the prostitution business when we're doing everything possible to impede prostitution, to impede the exploitation of women, children, boys, men, labor, sex trafficking. the internet is unfortunately the vehicle for this, and within the internet we are trying to be the sheriff.

>> reporter: as for violet's daughter -- >> it has wrecked her life. >> reporter: rescued in a police sting, she is currently at a safe house, getting the help she needs after missing for more than three years. >> reporter: you never stopped looking for her? >> never. >> reporter: making her one of the lucky ones. cnn, minneapolis, minnesota. >> it turns out ordering a girl for sex can be just as simple as ordering a pizza, sadly. in part 2 of her series, deb looks at how pimps are ewiyo use internet to sell girls and confronts a lawyer for backpage.com. >> how would you feel for example if you were a mother and saw an ad like this, or like this. this girl says she is 19. if you saw your daughter like this. >> part 2 of the series airs next saturday night right here 7:00 eastern on cnn.

[ applause ] but in many ways, the path forward for this next generation is far less clear. i mean what exactly do we do about children who are languishing in crumbling schools? what about kids growing up in neighborhoods where they don't have opportunities worthy of their dreams? what about the 40% of black children who are overweight or obese, or the nearly one in two who are on track to develop diabetes in their lifetimes? what court case do we bring on their behalf? what laws can be passed to end those wrongs? you see today the connection between our laws and our lives isn't always as obvious as it was 50 or 150 years ago. and as a result, it's sometimes easy to assume that the battles in our courts and our legislatures have all been won. it's tempting to turn our focus

solely to what is going on in our own lives and our own families and just leave it at that. and make no mistake about it, change absolutely starts at home. we know that. it starts with each of us taking responsibility for ourselves and our families. because we know that our kids won't grow up healthy until our families start eating right and exercising more. that's on us. >> first lady there talking about the importance of being healthy and the importance of family. of course she has the eat healthy initiative. she is speaking tonight at the congressional black caucuses foundation phoenix awards dinner where they honor four people who are making a difference. and of course addressing the issues facing african-americans. first lady of the united states speaking in washington. continue watching live if you want to watch at cnn.com/live. meantime, coming up tomorrow, don't method miss "global lessons. . putting america to work." it airs at 8, and 11 eastern and
